What is the subnet mask for 7?

What is the subnet mask for 7?

Understanding CIDR Subnet Mask Notation

Subnet Mask CIDR Prefix Number of /24 networks /8 65,536 /7 131,072 /6 262,144 /5 1,048,576

What is the 7th subnet range?

The seventh subnet ranges from the network ID of 172.16. 0.96 to the broadcast ID of 172.16. 0.111.

What is 32 subnet mask?

Generally speaking, /32 means that the network has only a single IPv4 address and all traffic will go directly between the device with that IPv4 address and the default gateway. The device would not be able to communicate with other devices on the network.

How do I find my subnet mask?

  1. In the Windows search fields, type cmd, to open command prompt.
  2. Press Enter.
  3. Type ipconfig/all press Enter.
  4. Find your network settings.
  5. Your PC’s IP address and your network Subnet Mask and Gateway will be listed.

What is subnet mask in IP address?

A subnet mask is a 32- or 128-bit number that segments an existing IP address in a TCP/IP network. It is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network. Once given the IP address and its subnet mask, the network address (subnet) of a host can be determined.

Is 255.0 255.0 a valid subnet mask?

A subnet mask distinguishes the network identifier from the host identifier in an IP address, but is not restricted by the same rules as the class-based method. A subnet mask, like an IP address, is made up of four numbers. These numbers can range from 0 to 255. 0.0 is a valid subnet mask as opposed to 255.0.

What is the subnet mask 255.255 255.0 in binary?

Convert the subnet mask to binary. In this example, the binary representation of 255.255. 255.0 is: 11111111.11111111.

Which is the magic number for subnet number?

Again, use the magic number. By adding the magic number to the interesting octet of subnet number and subtract 1. In this example, the magic number is 256 – 252 = 4, 100 + 4 – 1 = 103. Put the result from previous step in broadcast number of the interesting column.

How are IP addresses broken down into subnets?

Because the shortage was recognized years ago, developers came up with a way to split up an IP address into smaller networks called subnets. This process, called subnetting, uses the host section of the IP address to break it down into those smaller networks or subnets. Generally, an IP address is made up of network bits and host bits:

When is a subnet mask part of the network?

Whenever a bit in a binary subnet mask is 1, then the same bit in a binary IP address is part of the network, not the host. Since the octet 255 is 11111111 in binary, that whole octet in the IP address is part of the network.

What happens when a packet arrives on a subnet?

When a packet arrives on the subnet (from the local subnet or a remote network), and it has a destination address of, your computer will receive it from the network and process it. Almost all decimal subnet masks convert to binary numbers that are all ones on the left and all zeros on the right.
